How to Replace a Bathtub with a Walk-In Shower

Planning Your Shower Project

Replacing a bathtub with a walk-in shower is a major project, but it can be a great way to update your bathroom and create a more accessible space. Before you get started, there are a few things you need to do to plan your project.

Determine the size and shape of your shower

The first step is to determine the size and shape of your shower. The size of your shower will depend on the size of your bathroom and the amount of space you have available. If you have a small bathroom, you may want to consider a smaller shower, such as a 30-inch by 30-inch shower. If you have a larger bathroom, you may have more options, such as a 42-inch by 32-inch shower or a 54-inch by 36-inch shower.

The shape of your shower is also important to consider. You can choose from a variety of shapes, including rectangular, square, and L-shaped showers. The shape of your shower will also depend on the layout of your bathroom.

Choose the type of shower pan you want

The next step is to choose the type of shower pan you want. Shower pans come in a variety of materials, including acrylic, fiberglass, and tile. Acrylic and fiberglass shower pans are lightweight and easy to install, but they are not as durable as tile shower pans. Tile shower pans are more durable, but they are also more difficult to install.

When choosing a shower pan, you also need to consider the height of the pan. Standard shower pans are about 5 inches high, but you can also find shower pans that are lower to the ground. Lower shower pans are easier to get in and out of, but they can be more difficult to clean.

Select the shower fixtures you want

The next step is to select the shower fixtures you want. Shower fixtures include the showerhead, the shower controls, and the shower drain. You can choose from a variety of different showerheads, including handheld showerheads, rainfall showerheads, and body spray showerheads. You can also choose from a variety of different shower controls, including single-lever shower controls and multi-function shower controls.

When choosing shower fixtures, you need to make sure that they are compatible with the type of shower pan you have chosen. You also need to make sure that the shower fixtures are the right size for your shower.

Decide how you want to drain your shower

The final step is to decide how you want to drain your shower. You can choose from a variety of different shower drains, including floor drains, wall drains, and curbless drains. Floor drains are the most common type of shower drain, but they can be difficult to clean. Wall drains are a good option for small showers, and they are easier to clean than floor drains. Curbless drains are a good option for large showers, and they provide a more seamless look.

3. Level the shower pan. The shower pan must be level in order for the shower to drain properly. Use a level to check the pan and make any necessary adjustments.
4. Install the shower pan flange. The shower pan flange is a metal ring that helps to keep the shower pan in place. It is installed around the edge of the shower pan and secured with screws.
5. Connect the shower pan to the drain. The shower pan must be connected to the drain in order for the water to drain properly. The drain is typically located in the center of the shower pan. Connect the drain to the pan using a PVC pipe.

Installing the Shower Walls and Door

The shower walls and door are the most visible parts of your shower, so it’s important to choose materials that you like and that will withstand the elements. Here are the steps involved in installing the shower walls and door:

1. Install the shower walls. The shower walls are typically made of fiberglass or acrylic. They are installed by attaching them to the studs in the wall with screws or nails.
